Description

DEVICE FOR CLEARING YARN FAULTS
Technical Field
The invention is related to a device comprising an optical sensor system, to clear both the thick and fine faults in chenille yarns as well as very thick and fancy yarns used for knitting and weaving, which has been developed to clear, the smallest fault size in very high speeds and to clear the fine count yarns which cannot be previously cleared in similar systems, by using a specially produced photodiode. The device of the invention is specifically used during the winding stage in the yarn production plants before the yarn is sent to the weaving or knitting.
Prior Art
Yarn fault clearing devices have been used in the sector for a long time. These are mostly used in clearing thin yarns produced by a short fiber system and are installed on automatic winding machines. These kinds of winding machines contain various functions in a considerably complex head system such as detecting the fault, cutting by a cutter and air bender (splicer). Thus, the yarn clearing device must be located in a very confined area. Therefore, the blade/magnet system which performs the cutting operation in the device must be kept small. Thus, it is not possible to cut thick yarns.
In the present devices, mostly the very thick yarns can be cleared since the sensing photodiode is not sensitive enough. In the machines that can clear the thin yarns, when the yarn gets thicker, it can’t be cut due to the smallness of the blade system.
The summary of the application number 2000/02006 shaped as the result of technical research: a device to detect the faults on the yarn during production that comprises a detecting device and the brake deflector mechanism of the yarn and the cutting mechanism of the yarn on the upper and lower part of the detecting device, respectively. The device consists of a drum that is located between two shoulders and on which the yarn passes in a substantially strained condition and partially wound up thereon and thus wherein the helical (spiral, helix) effect is reduced since it is pressed on the drum. Outside the drum, there is a transparent unit which emits light and contains an optical sensor (detector). Thus, the light beam emitted from the light emitting unit projects the yarn on an optical sensor which continuously detects the amplitude of the shadow of the yarn. When the optical sensor detects an increase or decrease in the lateral dimension of the yarn with respect to a predetermined threshold value, the yarn is stopped, cut and the faulty part is removed.
As seen, the system is related to detection and remedy of the yarn fault, however it does not mention an embodiment that can solve the above-mentioned disadvantages.
Consequently, there is a need to enhance the related technical field due to the above mentioned problems and since the present solutions are not sufficient in the matter at hand.
Object of the Invention
The invention aims to provide an embodiment having different technical features that bring a new initiative in this field as opposed to the embodiments used in the current technique.
The primary objective of the invention is to provide a device that can be installed on the semi automatic winding machines on which manual air splicers can be mounted and that enables cutting thin yarns along with the very thick yarns. Removing the lens group of the device enables reducing the dimensions of the calibers which limits the light beam of the led. Reducing the dimensions of the calibers make it possible to fix with one screw by also engaging to the latches on the main body. As a result, the size of the yarn clearing sensor was completely reduced and this enabled connection to some fully automatic winding machines in the long term even though the most optimum usage is provided for semi-automatic winding machines.
An object of the invention is to enable clearing thinner yarns at higher speeds (1200 meter/minute flow rate) by a photodiode with a sensor sensitivity up to 0,72 A/W. The photodiode used in the old system only has 2 legs and the light beam received from the led is projected onto the photodiode by a lens. The sensitivity value of the photodiode used in the device of the invention does not require use of this lens system; thus, the lens group positioned in-between which causes the size of the device to increase is removed.
Another object of the invention is to provide a device that is equipped with a magnet system powerful enough to cut both the thick and the thin yarns and that is made of special production Tungsten Carbide alloy material. Cutting problem is not experienced even if the yarn is thick. This provides an advantage, but it requires to keep the size big. Thus, the device of the invention can be optimally connected to the semi-automatic winding machines. However, with the above mentioned changes, there is a possibility to connect to the fully automatic winding machines in the long term.
In order to achieve the objects mentioned above, the invention is a yarn fault clearing device that enables clearing faults of both the thin and the thick yarns, characterized by comprising;
• a Power Unit which supplies power to the system,
• a Programming Unit which sends signals to the optical unit to adjust and control the desired thickness values on the yarn,
• an Intermediate connection unit that runs the magnet / blade system and that simultaneously enables connection of the optical unit to the system,
• an Optical Unit Comprising, o a multilayered and filtered main electronic board, (today, almost every business uses electronically equipped machines and these systems transmit very noisy signals to the system if not properly grounded. As a result of this, some integrated circuits may burn out. In order to prevent this, special filter integrated circuits are added to the main circuit board).
o a high sensitivity photodiode with 14 terminal legs that enables reading the light beam received from the transmitters, (the photodiode used in the old system has only 2 terminal legs and the projection of the light beam received from the led on the photodiode was performed through a lens. The sensitivity value of the new photodiode does not require use of this lens system; thus, the lens group positioned in-between that increases the dimensions of the device is removed. Removing this lens group enabled reducing the dimensions of the calibers that limit the light beams of the led. Reducing the size of the calibers made it fixation possible with only one screw by also engaging to the latches on the main body. As a result, the size of the yarn clearing sensor was completely reduced and this enabled connection to some fully automatic winding machines in the long term even though the most optimum usage is provided for semi automatic winding machines.)
o a blade driving magnet with high ohm value and the blade / spring system that enables cutting the yarns (the blade edges made of D2 steel used in the old systems fall short in cutting some thick and/or fancy yarns having less twist and a lot of filaments. As a result, the fault on the yarn was detected and the blade was actuated, but the winding continued without clearing the fault since it couldn’t be cut. To solve this problem, the blade tips are converted to specially produced Tungsten Carbide tips.)
The structural and characteristic properties and the entire advantages of the invention will be better understood by the figures given below and the detailed description provided by referring to said figures and therefore if any assessment is carried out, it must be carried out by taking these figures and the detailed description into consideration.

In this detailed description, the preferred embodiments of the invention are described in a non limiting way whatsoever to provide a better understanding of the subject.
The invention is related to an optical sensor system to clear both the coarse and fine faults in chenille yarns and the yarns used for knitting and textiles produced in very coarse and fancy fabrics and to a device developed to clear the smallest fault size in very high speeds and to clear the small number thin yarns, which cannot be previously cleared in similar systems, by a specially produced photodiode (5). Moreover, the photodiode used in the old system has only 2 terminal legs and the projection of the light beam received from the led on the photodiode was performed through a lens. The sensitivity value of the new photodiode (5) does not require use of this lens system; thus, the lens group positioned in-between that increases the dimensions of the device is removed from the device of the invention.
The device of the invention performs the yarn cutting operation basically in two stages. In the first stage, the yarn passes between the light beams received from the transmitter led (3) and the high sensitivity reader photodiode (5). In this stage, the thickness differences on the yarn are read. In the second stage, depending on the values read on the photodiode (5), if the thickness of the yarn is outside the pre-adjusted values, the magnet (1 ) is energized and the magnet (1 ) in the blade (2) section pushes the blade (2) by a rod and cuts the yarn.
While the yarn is passing by the reader photodiode (5), the increase or decrease in the millicandela values received from the led reflected on the photodiode (5) by the thin or thick locations called faults are controlled if they are between the limit values entered to the programming unit. If they are outside the limit values, the blade (2) connected magnet (1 ) is energized and the faulty location on the yarn is cut. In the programmer, both the thickness/thinness limits and the length of said thick/thin location is limited. Thus, the system activates the blade by reading the length of the thick or thin region.
Said transmitting led (3) can provide a light power up to 3000 millicandelas. The photodiode (5) is developed with 14 terminal legs, the light beam received from the transmitting led (3) is read to clear the very thin fancy type yarns and information is sent the main electronic circuit board (9). The main electronic circuit board (9) has a multilayered structure with filters against shocks. Today, almost every business uses electronically equipped machines and these send very noisy signals to the system if not properly grounded. As a result of this, some integrated circuits on the main electronic circuit board (9) may burn out. In order to prevent this problem, special filter integrated circuits are added to the main circuit board.
The programmer to which the optical device of the invention is connected operates with the power unit and the intermediate connection unit.
The Power Unit is the unit that provides energy to the system. Inside, there is a transformer, a main electronic circuit board, fuses and on/off switch. The Programming Unit is the device that sends signals to the optical unit to adjust and control the desired thickness value on the yarn. It consists of a main electronic circuit board, a liquid crystal screen and a keyboard. The intermediate connection unit is the unit that operates the magnet/blade system and that simultaneously enables connection of the optics to the system.
The optical unit contains a multilayered main electronic circuit board (9), the blade driver magnet (1 ) with high ohm value and the blade/spring system, specially produced high sensitivity photodiode (5) with 14 terminal legs and the 3000 millicandela transmitting led (3).
In the device of the invention, there is the blade protector (4) that enables cutting the yarn when the blade (2) is actuated. Moreover, in the device, there is the photodiode protecting glass (6), calibration upper led (10) that indicates auto-calibration, the cutting group carrying body (1 1 ) that carries the magnet-blade system, yarn calibers (12) with 3/5/7/10 mm grooves which are changed depending on the thickness of the yarn and which limits the light beam received from the led and the photodiode carrier (13) that consists of the stand system carrying the high sensitivity photodiode (5).
